Research on the neural bases of cognitive deficits in autism spectrum disorder (ASD) has shown that working memory (WM) difficulties are associated with abnormalities in the prefrontal cortex. However, few studies have examined the impact of cognitive load on WM and its neural underpinnings in children and adolescents. We used fMRI and an n-back task with four levels of difficulty to compare the cortical activation patterns associated with WM in children with and without ASD across cognitive load. Findings revealed impaired modulated activity as a function of cognitive load in prefrontal and parietal cortices in children with ASD relative to typical controls. Results suggest that children with ASD rely mainly on posterior brain regions associated with lower-level visual processing, whereas controls showed activity in frontal lobes related to the classic WM network. Findings will help guide future longitudinal work by localizing areas of vulnerability to developmental disturbances.

Master of Science / Department of Special Education, Counseling and Student Affairs / Fred Bradley / The purpose of this report is to review available literature that identifies various psychological issues collegiate student-athletes may face and how medical professionals, specifically certified athletic trainers (ATCs), are prepared to manage these psychological issues. Considering ATCs are in constant interaction with student-athletes in comparison to other medical professionals it is crucial that research is being completed to make sure athletic trainers are properly caring for student-athlete and acting quickly and appropriately to psychological issues. This report will review research on psychological aspects encountered by athletic trainers in contact with student-athletes, and; furthermore, the ATCs sense of comfort and competence in working with these issues. Questions may arise such as how well the ATC is able to assess the psychological issues and know when to assist or refer these matters, issues which may include training, competence, expectations, and ethical practice. Finally, the review of the research and literature in this area will lead to suggestions and implications for further research and continued understanding of the ATCs role in the psychological aspects of their work with student athletes.

Mindfulness-based wellness education (MBWE) is an 8-week program teaching formal mindfulness practices as a foundation for cultivating an awareness of one’s health or ill-health in the physical, social, emotional, ecological, vocational, mental and spiritual domains of human existence. It is designed as a health promotion intervention for individuals who are at risk of developing stress related problems, such as is the case of human services professionals. This dissertation focuses on teachers-in-training. Two groups of teacher trainees completed MBWE as part of an elective course focusing on stress and burnout. In comparison to control participants, who completed other optional courses, MBWE participants experienced improvements in mindfulness, health, and teaching self-efficacy. In one group, the intervention was also effective in reducing psychological distress and augmenting satisfaction with life. Interviews with participants after graduation revealed that although they struggled with independent mindfulness practice, they benefited from their participation in the class, which led to specific health behavior changes such as increased physical activity. Some participants reported that they relied on their mindfulness practices in times of crisis; others shared the knowledge they learned with their students and observed that this was an effective and beneficial response to the needs of their classrooms. Ideas for future inquiries include the need to explore factors influencing participants’ responses to the MBWE program and how to support on-going practice.

Popular music plays a significant role in the lives of most adolescents. The central question explored is whether three groups of adolescents (psychiatrically ill, depressed, and non-clinical adolescents) differed on self-reported data on: (a) the role of popular music in their lives, and (b) in their emotional reactions to music. The next question is whether the developmental issues of gender and personality consolidation, age, and school commitment simultaneously influence how the three groups of adolescents use music in their lives and in their emotional reactions to music. The last question is whether the three groups have significantly different music preferences in the five genres of popular (rap, pop/dance, heavy metal/hard rock, classic rock, and alternative). There were 126 subjects employed in this research. I created the Walker Music Questionnaire (WMQ) to explore the role and importance that music plays in the lives of the adolescents. A factor analysis found five factors (Introspection, Identity-Music, Discerning Music Identity, Fantasy-Rebellion, and Identity-Self). The Adolescent Semantic Differential Scales (ASDS) measured the adolescents’ emotional responses to 10 pieces of popular music representing the five genres described above. These scales are well known measures of emotional response and I added eight adjectives that represented adolescent issues. This measure was also factor analyzed and the three factors of Evaluation, Romance, and Potency emerged. Preference for the five genres was determined from the Adolescent Semantic Differential Scales. MANOVAS were done with both sets of factors derived from the WMQ and ASDS simultaneously using the developmental variables of age group, gender, personality, and school commitment. Psychological health was found to be a significant variable. Specifically, the role of music for the depressed group was significantly different from the other two groups of adolescents. The developmental issues that remained significant were personality and school commitment. Furthermore, the psychiatrically ill group reacted more emotionally to the music than the other two groups and this remained significant even when the developmental variable of personality was considered. The three groups were not differentiated by their preference ratings on the ASDS.

In this study the subjective experience of psycho-analytic essence is approached through an examination of conscious and unconscious representations of self-in-work (Dreyfus, 1991). The study begins with an heuristic identified as the psycho-analytic moment, a transitory self-state arising in the course of conducting a psycho-analysis and felt to correspond to occasions of right, expert, good or exemplary therapeutic practice. The study advances to an examination of the lived experience of clinical psycho-analysis through a set of structured and unstructured interviews with two psycho-analysts. The study’s general approach incorporates a revised version of Goethe’s delicate empiricism as adapted by Hoffman (1989). The methods for interviewing participants and for analyzing transcripts were designed to access unconscious communications regarding subjective experience. Interview procedures combined phenomenological and free-associative narrative techniques: Procedures for transcript analysis were developed from literary studies, psycholinguistics, psycho-analysis and grounded theory. The analysis of participants’ utterance led to the hypothesis that an unconscious configuration of inference and memory gives shape to the subjective experience of composite elements of psycho- analytic practice. This hypothesized coherence of unconscious memory and process structures is identified as a structural metaphor. The structural metaphor is posited to underwrite the verisimilitude of lived experience, personal idiom and aesthetic within the clinical encounter. Thus, the structural metaphor is hypothesized to shape not only the psycho-analyst’s representations of his or her way of being-in-work and linguistic deportment within the interview setting, but to also shape the subjective experience of psycho-analytic practice. Thus reconsidered, the psycho-analytic moment is viewed as an existential moment in the ongoing phenomenology of lived experience, occasioned by a convergence of unconscious identity and experience within the clinical field. This existential moment is taken to be indicative of the presence of something essential about self, work or self-in-work, as a result of a set of psychological, affective and visceral factors that arise in this moment of convergence. However, the psycho-analytic moment is assigned little epistemic value in identifying properties of psycho-analysis as a discipline or a practice, instead reflecting the structural metaphor that underlies the experience of that practice.

Children with fetal alcohol spectrum disorders (FASD) have deficits across many cognitive, behaviour and social domains. However, despite social difficulty being proposed as a main deficit following prenatal alcohol exposure, the nature of their deficient social behaviour is largely unknown. One process that may underlie difficulties in social functioning is poor social cognition, which refers to one’s understanding of the self, others and social world. The primary goal of this dissertation was to determine whether social cognitive deficits represent a core disability underlying the socio-behavioural problems of FASD using a bottom-up approach. The first level of this approach is represented by face processing. Global and independent face feature processing was compared between FASD and normal controls (NC) using experimental and clinical measures. Eye gaze processing was investigated next using experimental and clinical tasks. At the highest level of the bottom-up approach, social perspective taking, including theory of mind and empathy were examined, along with how these abilities related to parent-rated behaviour. Finally, the lowest level consisted of specific aspects of the social neural network. White matter in three limbic pathways was investigated using diffusion tensor imaging (DTI). Results generally supported the bottom-up approach of social cognition in FASD. These children showed impaired processing of face features, when matching mouth shapes and partially occluded identity, compared with NC. The FASD group was slower to process gaze and arrow cues, suggesting impaired attention shifting. Children with FASD also showed impairments in social perspective taking, including understanding false beliefs and empathy, and these impairments were related to parent-rated attention and social problems, and autistic-like traits. Deficits in theory of mind got worse with age in FASD and empathy showed distinct sex-related differences. Although no group differences were observed on DTI indices, groups did show different age-related changes in white matter. In conclusion, deficits at each level of the current bottom-up approach may underlie the social impairments in FASD and may contribute to their broader social behavioural phenotype. The results from this dissertation have potential to inform clinical practice and lead to more effective diagnostic and treatment approaches in FASD.

Social competence and positive self-concept are essential to future adaptive outcomes and overall well-being; but children and adolescents with learning disabilities (LD) frequently struggle in these domains. This dissertation examined changes in the social competence and self-concept of campers with learning disabilities (LD), within a specialized summer camp, with particular focus on friendship development. The dissertation is presented in two manuscripts, which will be submitted for publication. The objective of the first manuscript was to examine changes in campers’ social skills, social acceptance, self-worth, and self-esteem, within the context of summer camp, as reported by parents and campers. Parental reports indicated small gains in social skills, social acceptance, and self-worth from the beginning to the end of camp; with gains in social acceptance and self-worth maintained four to five months later. Campers did not report changes in any domains. Parents and campers reported declines in camper self-esteem at follow-up. In general, campers with LD+ADHD exhibited smaller gains in social competence and self-concept, than those with LD. Results are discussed in relation to theoretical frameworks and existing camp and LD research. The objective of the second manuscript was to investigate campers’ friendship development, within the summer camp context. Many campers reported having high-quality, reciprocal friendships at the beginning of camp. Campers reported more reciprocal friendships after camp, but these were not maintained at follow-up. Campers also reported having a best camp friend by the end of camp, and this relationship was maintained at follow-up. In terms of friendship quality, campers reported increased closeness by the end of camp and conflict ratings were low, overall. This study examined factors predicting changes in social competence. High-quality, reciprocal friendships predicted changes in campers’ social acceptance, according to parents. Similarly, reciprocal friendships predicted changes in camper reported social acceptance. These results highlight the inter-connections between friendship and aspects of social competence. Camp attendance was found to be a relevant factor in friendship development and quality. The concluding chapter discusses social competence, friendship, and self-concept outcomes for campers with LD within the context of a specialized summer camp. The implications of the findings for present theory and clinical practice are discussed, including specific recommendations for this camp’s structure and program evaluation procedures.

Objective: Past research indicates that comorbid anxiety and depression in youth is associated with greater functional impairment than anxiety alone. To elucidate those factors which may increase vulnerability to depressive disorders, the current study examined several clinical correlates (i.e., feelings ratings, parental psychopathology symptoms, and family functioning) of comorbid depressive symptoms in young anxious children. Method: Sixty-eight children, aged 6 to 10 years (M = 9.06, SD = 1.10), and caregivers completed measures assessing child depressive symptoms. Furthermore, children completed self reports of anxiety symptoms, feelings ratings, and family functioning, while caregivers completed self reports of psychopathology symptoms and family functioning. Predictors of child depressive symptoms were examined separately for girls and boys. Results: In females, hierarchical regression analyses revealed that, after controlling for anxiety, higher sadness and lower positive feelings accounted for 30% of variance in child-reported depressive symptoms. Further analyses indicated that child-reported overall family dysfunction moderated the relationship between positive feelings and depressive symptoms, such that high family dysfunction increased the risk of depressive symptoms in females with low positive emotions. In males, hierarchical regression analyses revealed that, after controlling for anxiety, higher negative/hostile feelings and child-reported overall family dysfunction accounted for 19% of variance in child-reported depressive symptoms. Further analyses of family functioning in males revealed that child-reported family cohesion and conflict were negatively and positively correlated, respectively, with depressive symptoms. Family dysfunction did not moderate the relationship between feelings ratings and depressive symptoms. The only significant predictor of caregiver-reported child depressive symptoms, for males only, was caregiver self-reported overall psychopathology symptoms. Further analyses indicated that, for males, caregiver depression and hostility symptoms correlated positively with caregiver-reported child depressive symptoms. Conclusions: Different patterns of emotion and family functioning predicted self-reported depressive symptoms in males and females. Self and caregiver reports of child depressive symptoms were not related, with only caregivers’ psychopathology symptoms predicting their reports of child depressive symptoms. Results suggest the importance of assessing child-reported feelings and family dysfunction, and parental symptomatology, of clinically anxious children. To prevent future depressive disorders in these children, different targets of intervention for males and females may be warranted.

Substantial evidence indicates that maltreatment places abused children at great risk for illiteracy and damaging self-perceptions of competency and worth. Given that academic ability and self-concept are reciprocally related and mutually reinforcing, it was hypothesized that participation in an intensive literacy intervention would positively impact the reading, writing, and related self-perceptions of maltreated Struggling Readers from the Ontario Child-Welfare system. Using a mixed methods approach, 24 participants (ages 14-24) completed achievement and self-perception measures and were interviewed about their literacy experiences and views, pre and post intervention. Repeated measures analyses and pairwise comparisons measured the impact of intervention on the literacy skills and related self-evaluations of these youth and assessed how the literacy skills and related self-evaluations differed from maltreated youth without reading difficulties (n = 22). Interviews were analyzed thematically. Results converged to provide empirical support for the benefits of literacy intervention on skill and self-perception development for this high risk group of youth. Qualitative analyses further revealed unanticipated, dramatic and meaningful life changes. Participants manifested improved communication and metacognitive skills, increased autonomy and internal motivation, and amplified feelings of empowerment and hope for the future.
